Abstract 2D materials possess wide‐tuning properties ranging from semiconducting and
metallization to superconducting, etc., which are determined by their structure, empowering …

AVO 4 orthovanadates are materials of fundamental and technological importance due to
the large variety of functional properties exhibited by them. These materials have potential …

Methylammonium lead iodide perovskites are considered direct bandgap semiconductors.
Here we show that in fact they present a weakly indirect bandgap 60 meV below the direct …
